Final answer:
The franchise owner's firm experienced a loss of $40,000.
Step-by-step explanation:
Accounting profit is the total revenues minus explicit costs. In this case, the franchise owner earned $30,000 in profits last year, so her accounting profit is $30,000. However, economic profit takes into account both explicit costs and implicit costs. Implicit costs are the opportunity costs of using resources for one purpose instead of another.
Since the owner knows that most of her business acquaintances earned at least $70,000 in profits in similar franchises, it suggests that her implicit costs are higher than $30,000, resulting in a lower economic profit or even a loss.
